Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505926, here are decompositions:

7 + 505919 = 505926
19 + 505907 = 505926
59 + 505867 = 505926
103 + 505823 = 505926
107 + 505819 = 505926
149 + 505777 = 505926
163 + 505763 = 505926
167 + 505759 = 505926

Showing the first eight; more decompositions exist.
